WATER-HEATER AND STEAM-BOILER.

AppIcaton filed October 11, 1916. Serial 110.125,118.

To' all whom it may concern:

Be 1t known that` I, MAJOR E. BEARING, a citizen of the United States, residing at Salt Lake City, county of Salt Lake, and State of Utah, have invented certain new and useful Improvements in' Vater-Heaters and Steam-Boilers, of which the followlng is a specicaton.

This invention relates to water heaters and steam boilers of that general class wherein a heating chamber or chambers are immersed in the water contained within the shell and are internally heated by heat producing means.

My object is to provide an improved water heater and steam boiler of the general class set forth wherein a maximum heating effect is obtained by the exposure of a maximum heating surface to the water and the use of a minimum amount of heat whether generated'electrically or produced by steam, gas, oil, gasolene, or other heat producing means.

A further object is the provision of a wa ter heater and steam boiler, constructed in an improved manner whereby the water and the heat producing means are insulated from the external air to thereby minimize radiation and insure a maximum heating effect on the water by minimizing loss through radiation.

Another object is the provision of a water heater and boiler wherein the heating devices are self-contained with a hollow removable section coperatively related to the heating cells or chambers in a novel manner, rendering it possible to place in position, or remove, the heating'devices as an entirety.

My invention resides, still further, in a shell or hollow heating element of convolute form whereby the heat from any given part of the heating element or elements, device, or devices, has access to, and heats, the complete convolute heating device. This form of heating device also enables a maximum area to be in contact with the water and thereby obtains a maximum heating effect.

Another improvement provided by my invention is the disposition of the heating elements or means in the lower portion of the convolute heating d'evice whereby the heat which rises from the heating elements or means, attains the full height of the hollow heating device and the maximum heating effeet is thereby obtained,

The hollow convolut'e heater comprises alternate heating chambers or spaces and wa- Specification of Letters Patent.

ter spaces, the former being closedat their tops and the latter at their bottoms. The hollow attachable and removable section carries the heating elements or means in such arrangement or disposition that they enter yor are exposed to the open lower ends of the heating chambers when said removable section is secured in position.

Preferably the heating elements or means comprise resistance coils carried by insulating .material and-attached to the removable. section, with a. trunk conduit and branches containing the leading in electric wires for the resistance elements, self-contained with and bodily carried by the removable section: However, in its broadest aspect the invention is not limited to the use of resistance coils or elements as the heating means, as I may provide means, carried by the removable section, for heating the convolute heating device by steam, gas, oil, gasolene, or other heat producing means.

The embodiment of the invention hereinafter described and shown in the accompanying drawings is to be considered as illustrative, rather than restrictive, of the scope thereof, as modifications may be resorted to within the principle of the invention.

In the accompanying drawings:

Figure 1 is a vertical section;

Fig. 2, a section on line 2-2 of Fig. 1;

Fig. 3,21- section on line 3-3,of Fig. 1; and

Fig. 4, a detail top plan of the removable bottom section.

The inner and outer shells 1 and 2 are separated by a sealed space 3 which may contain -dead air or be a vacuum. The water supply enters through pipe Lbunder suitable valve control, and the hot water or steam, under suitable control, passes out through the outlet 5. The device may be used either as a water heater or a steam boiler according to whether it is fully, or only partially, filled with water. An ordinary gage glass 6 with suitable valves, may be employed. Any suitable base orstandard Z may be used to support the shells 1 and 2. The shell .2 has an outstanding flange 8 by which 1t 1s connected to the shell 1 at the bottom there- Secured to the bottom plate or piece 9 is a hollow fixed bottc m section 11 which may tially annular form having a tapered .inner l ends of Awater-containing shell 2 from the external air, thereby minimizing loss by radiation. The convolute heater 10 is composed of heating chambers 13 closed at their tops 14 and separated by water cells or'spaces-15 which are open -at their upper ends 16. Braces 17 and 18 .are provided to hold the heating chambers and water cells rigidly in relation to each other. Asbest seen in Fig. 3, the convolute heater l0 tapers at the its coil as at 19 and 20. The fixed bottom section 11 is of substanface or margin 21.l .Fittedv snugly into the tapered interior 21 is a hollow removable bottom section 22 havin atapered periphery adapted to fit the sur ace 2 1. The 'section 22 h as a Bange 23 which overlaps or interlies the section 11. Releasable clamps 24 on eitherthesection 11 or section 22, constitute means for firmly holding the-section 22Ain position, subject to quick removal when desired. The section 22 is hollow, its interior 25 com rising either a vacuum-or adead airf-v-space or purposes of heat insulation. Surmounting the section 22 is a plurality of electrical resistance sectionsvorunits 26, 27,28 which lie in and are secured to insulatingblocksor-bed ieces 29 fixed to the section 22 so that the bed pieces and the resistance elements are -self-contained with and may be bodily removed with the bottom sec- `tfion22.' -The resistance units 26, 27, 28 are arrange'djlin convolute form so that they will; ente'zthe bottoms of the heating chambers`f13. Carried by the bottom section 22 is a"f"t"runk conduit 30 having pairs or branches 31 through which the electric conductors pass and are connected to the respective resistance elements 26, 27, 28. For that purpose binding posts 32 may be provided, said -posts being carried bythe bed pieces 29 and constitute terminals of the electric conducv tors. The trunk conduit 30 may extend to a convenient position as shown at 30a f or letting in electric conductors from any suitableI source.

A valved drain ipe 33 may be provided, leadin from the ottom of the shell 2.

In p ace of theresistance elements 26, 27, 28 I may substitute gas, oil, gasolene, steam, or other burners or heatin p means which would be self-contained wit the section 22 and adapted to Abe bodily removed with it. -The entire interior, 13, of the convolute heatin coil 10 being exposed to the plurality ofIieating devices 26, 27, 28, heat from each of said devices has access to all parts of the interior of the said device 10. F ur thermore, the location of the heating devices 26, 27, 28 in the lower portions of the chambers 13 enables the maximum heating eiect to be' obtained, as the heat rises in said chambers because the walls of said chambers are in contact, on both sides, with the water contained in the shell 2. The heatii means being self-,contained with the remova le bottom section 22, when the clamps or catches 24 are released they may be quickly removed with the section 22 for purposes of inspection or repair thereto or to enable access to be had to the chambers 13.
